Apache HTTP server is the most popular Web server in the world. It is a free open source and cross-platform HTTP server that provides powerful features and can be extended through a variety of modules. The following instructions describe how to install and manage an Apache Web server on a CentOS 7 machine.
Install Apache
Apache is available in the default CentOS repository and is easy to install. On CentOS and RHEL, Apache packages and services are called httpd. To install the package, run the following command:
Sudo yum install httpd
After the installation is complete, enable and start the Apache service:
Sudo systemctl enable httpdsudo systemctl start httpd
If you are running a firewall, you also need to open HTTP and HTTPS ports 80 and 443:
Sudo firewall-cmd-permanent-zone=public-add-service=httpsudo firewall-cmd-permanent-zone=public-add-service=httpssudo firewall-cmd-reload
We can check the status and version of the Apache service in the following ways:
Sudo systemctl status httpd
Output:
Httpd.service-The Apache HTTP Server Loaded: loaded (/ usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2018-04-26 07:13:07 UTC; 11s ago Docs: man:httpd (8) man:apachectl (8) Main PID: 3049 (httpd) Status: "Total requests: 0; Current requests/sec: 0 Current traffic: 0 B/sec "CGroup: / system.slice/httpd.service ├─ 3049 / usr/sbin/httpd-DFOREGROUND ├─ 3050 / usr/sbin/httpd-DFOREGROUND ├─ 3051 / usr/sbin/httpd-DFOREGROUND ├─ 3052 / usr/sbin/httpd-DFOREGROUND ├─ 3053 / usr/sbin/httpd-DFOREGROUND └─ 3054 / usr/sbin/httpd-DFOREGROUNDsudo httpd-v
